Where would you go to find accountant-only features such as Prep for taxes or Write off invoices?

The correct choice is to access the Accountant Tools for features specifically designed for accountants, such as "Prep for taxes" or "Write off invoices." This area is tailored to suit the needs of accounting professionals, providing them with tools that facilitate tax preparation and account management.

Accountant Tools typically include functionalities that streamline the accounting workflow, allowing accountants to efficiently manage client accounts and perform necessary actions like invoicing adjustments or preparing for tax submissions. These features are not generally available in the other sections since Client Tools typically focus on client interaction, Account Settings are more about general account preferences, and Reporting Tools are oriented towards generating financial reports rather than providing specific accounting functionalities.
